Autochrome is a tool to synthesize realistic film grain. It is based on the research of Newson at al (2017).

The name Autochrome is based on the early color photography process Autochrome Lumière.

Requires Python 3.10

py -3.10 -m venv venv

Install the package:

pip install autochrome@https://github.com/beatreichenbach/autochrome/archive/refs/heads/main.zip

python -m autochrome --gui
